Configuring the GPRS Tunneling Protocol
Cisco Systems’ GGSN/P-GW/S-GW supports both GTPP- and RADIUS-based accounting. The accounting protocol is
configured on a per-APN basis.
configured on a per-APN basis.
When the GTPP protocol is used, accounting messages are sent to the Charging Gateways (CGs) over the Ga interface.
The Ga interface and GTPP functionality are typically configured within the system's source context. As specified by
the standards, a CDR is not generated when a session starts. CDRs are generated according to the interim triggers
configured using the charging characteristics configured for the GGSN, and a CDR is generated when the session ends.
For interim accounting, STOP/START pairs are sent based on configured triggers.

GTPP version 2 is always used. However, if version 2 is not supported by the Charging Gateway Function (CGF), the
system reverts to using GTPP version 1. All subsequent CDRs are always fully-qualified partial CDRs. GTPP version 0
is not supported.

GTPP is configured at the routing context level. Some of the configurables associated with GTPP are Attributes,
Charging Agent, Deadtime, etc. The GTPP configuration commands vary according to the services configured, for
example, the commands used for GGSN might differ from what is configured for P-GW. For more information on the
configuration commands, refer to the Command Line Interface Reference.

Important:
Commands used in the configuration examples in this section provide base functionality to the extent
that the most common or likely commands and/or keyword options are presented. In many cases, other optional
commands and/or keyword options are available. Refer to the Command Line Interface Reference for complete
information regarding all commands.

Configuring GTPP for ePDG
This section provides the GTPP configuration for ePDG.
1. Configure the accounting context in Call Control Profile level and also specify the accounting mode.
configure
context context_name
call-control-profile cc-prof_name
accounting-mode gtpp
end
When the accounting mode is set to GTPP, it indicates that the offline charging is enabled and Ga reference
point will be used for passing ePDG CDRs to CGF (if enabled).
point will be used for passing ePDG CDRs to CGF (if enabled).
2. Associate the call-control-profile with an accounting policy configured in the same context. Accounting policies
are configured through the policy accounting command in the Context Configuration mode.
